Procedure

A solution of (S)-tert-butyl 3-(4-amino-3-(4-aminophenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)pyrrolidine-1-carboxylate (0.075 g, 0.17 mmol) in CH2Cl2 (10 mL) was cooled in an ice-water bath. To this, 3-(trifluoromethyl)benzoyl chloride (0.025 mL, 0.17 mmol) diluted in CH2Cl2 (5 mL) was added dropwise. The reaction was allowed to warm to room temperature and left stirring for 4 hours, yielding the benzamide derivative (ESI-MS m/z [M+H]+ found 568.5, calculated 568.6). Boc-deprotection was completed through the addition of formic acid (5 mL) and concentrated HCl (0.5 mL) added dropwise directly to the reaction mixture. The reaction mixture was left stirring for 12 hours and then was concentrated in vacuo, resuspended in 50:50 H2O—CH3CN, and purified on a C18 column in CH3CN/H2O/0.1% TFA (1-100% gradient) to afford AD70. ESI-MS m/z [M+H]+ found 468.5, calculated 468.2.
